Struggling Carlton is set to be confronted on Friday night by a much more imposing Geelong defence than the makeshift one which leaked 22 goals to rampaging Sydney.

Full-back Tom Lonergan is almost certain to return after recovering from concussion, as is five-time All Australian Corey Enright (ankle).

Throw in another triple premiership star in Andrew Mackie, who has recovered from the sore back that saw him subbed out of the 110-point demolition at the SCG and the Cats will be short-priced favourites to get back on the winning list and extend their perfect record against the Blues at Docklands to 12-0.

"We're very confident that Lonergan will play and almost as confident that Enright will play as well," Geelong coach Chris Scott said on Wednesday.

"We'll clearly be cautious with the two of them - Tom because it's a head injury and we need to be absolutely sure, there can be no doubt at all if he takes the field.

"And Enright because he's one of our more experienced players, our older players, and we're really conscious of looking after those guys physically.

"If he plays we've got to be absolutely sure there won't be any negative ramifications in subsequent weeks."

In further good news on the injury front, star utility Allen Christensen is set to return through the VFL this weekend after finally recovering from a back injury suffered in the pre-season.

The loss to the Swans was sixth-placed Geelong's third on the road in 2014, although Scott was adamant that had more to do with the quality of the opposition than the rigours of interstate trips.

The other defeats were against ladder-leading Port Adelaide at Adelaide Oval and Fremantle at Patersons Stadium.

But even though the loss to Sydney ended up being the seventh biggest in club history, Scott said there was no way the club would just dismiss it as an aberration.

"I think that's the easy way out," he said.

"We review it thoroughly, we spend a lot of time on it, as painful as it was.

"There are some consistent things that are plain for everyone to see.

"Sydney had more than 100 possessions more than us in the game, that makes it very hard for our defenders to cover their forwards.

"That translates to 75 inside 50s which is a world record against us.

"We're all accountable at this footy club and everyone who was involved in that game made some serious mistakes and did some things that we need to rectify."
